Interfaces built from clear structure.

AI-agent SaaS for loan officers at financial companies. Chats with applicants to collect and analyze required documents, cutting review time. Shipped a PoC in two weeks and it was greenlit as an official in-house product. Now in production, already delivering results, and improving continuously.

A web payments service letting partner-merchant customers take zero-fee, zero-interest loans. Rebuilt the existing brand faithfully in Chakra UI and unified the user app and admin panel in a monorepo. Adopted by thousands of merchant stores.

A shared analytics platform for three major Japanese ranching companies. Visualizes IoT sensor data from cattle for producers, feed companies, and lenders. Adopted DevExtreme to handle large data tables and Turborepo to manage three parallel apps, cutting development time by roughly 50%.

A no-code platform for building and deploying ML models. Refactored PoC-quality code into reusable components. Adopted by multiple client companies, including firms in Japan.

An online stock-trading service in Mongolia. Led system testing with the central securities depository for Xac Bank's IPO, and managed task allocation for an external dev team alongside client-facing coordination.

Web presence for a new store-less mobile carrier in Mongolia. Built an online auction system for premium phone numbers that stayed stable under hundreds of thousands of concurrent users, running reliably for about two years.
